Build, change or debug local apps and publishable web apps, using the matching browser, common data or host contract. Not product help or System Skill editing; grants no execution authority.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Application development

Use the creation task's selected type or the original app's type when editing.
Omit `create_artifact.appType` to inherit that platform binding. In ordinary
conversations, new apps default to local; use web only when the user requests it.
Editing retains the original type. Converting requires a new app identity.

Read [the common data contract](references/common.md), then the appropriate
reference before choosing APIs:

- Local: [local guidance](references/local.md), [API contract](references/api.json)

- Web: [web guidance](references/web.md), [API contract](references/web-api.json)
  and [starter](assets/web/index.html). Apply this contract during generation,
  preview, unpublished desktop use and online use.

Build through `create_artifact` with a complete top-level index.html and relative
bundled paths. Include `orkas-app.json` in that same call, declaring every SDK
capability the app uses and, for data, its definition: a local app without it gets

How to install

The exact contents, by fingerprint

mdr add orkas-ai/orkas/web-app-sdk@sha256:7004afe2adc29a88

The line at the top of this page pins the label git:20261104.f8819b9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
